2005 PORSCHE CAYENNE S tire type

Practical Tips, Minor Repairs
307
Spare wheel
Warning!
Risk of accident. The wheel and tire size and
the tire quality of the spare wheel and normal
wheel may differ.
If a spare wheel that differs from the normal
tires is used, this may impair the driving
behavior.
fThe spare wheel must be used only over short
distances in cases of emergency.
For safety reasons, replace the tires before
the wear indicators appear (webs in the tire
grooves, 1/16 in. (1.6 mm) high).
fNever deactivate the Porsche Stability
Management (PSM) system.
fIf the tire on the spare wheel is older than
4 years, the spare wheel should be used only
in the event of a flat.
fAvoid hard acceleration and high cornering
speeds.
The maximum permitted speed is 50 mph
(80 km/h) if the mounted spare wheel differs
from the other three wheels on the car. This
maximum speed must not be exceeded
because of altered driving characteristics and
for reasons of wear.
fDo not use a spare wheel from a different vehi-
cle type.
fDo not mount the spare wheel from your car on a different vehicle.Removing spare wheel
Warning!
Danger of injury if the spare wheel is
removed improperly.
fRemove the spare wheel only when the spare
wheel bracket is locked.
fRemove the spare wheel from the spare wheel
bracket with care. The wheel is very heavy (approx. 77 lbs. (35 kg)).
1. Unscrew all five wheel bolts.
2. Remove the top wheel bolt.
Remove assembly aid from the tool kit and
screw in instead of the wheel bolt.
Remove the remaining wheel bolts.
Fitting spare wheel
fInsert wheel bolts and tighten by hand.
Remove assembly aid and screw in remaining
wheel bolt.
Initially tighten bolts in diagonally opposite
sequence so that the wheel is centerd.
fPlease observe the chapter “TIRE PRES-
SURES, COLD” on Page 361.
fAfter mounting the wheel, tighten all five wheel
bolts to 111 ftlb. (150 Nm).

Vehicle Identification, Technical Data Snow chains
1)
Snow chain clearance can be guaranteed only with the tire + rim combination marked
1).
The best possible handling characteristics are achieved when snow chains are fitted on all four wheels
of the vehicle. However, it is also possible to fit snow chains on only one axle (preferably the rear axle).
For safety reasons, vehicles with snow chains must not be driven faster than 30 mph (50 km/h).
fObserve the respective road traffic regulations.
fUse only Porsche-authorized fine-link cross-type or edge chains. Cayenne S Tires Wheel Rim offset Track
